7.5A Low Dropout Positive Adjustable Regulator

The RH1083M positive adjustable regulator is designed to provide 7.5A with higher efficiency than currently available devices. All internal circuitry is designed to operate down to 1V input-to-output differential and the dropout voltage is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1.5V at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the output voltage to 1%. Current limit is also trimmed, minimizing the stress on both the regulator and power source circuitry under overload conditions.

The RH1083M is pin compatible with older 3-terminal regulators. A 10μF output capacitor is required on this new device. However, this is usually included in most regulator designs.

Unlike PNP regulators, where up to 10% of the output current is wasted as quiescent current, the RH1083M quiescent current flows into the load, increasing efficiency.

The wafer lots are processed to our in-house Class S flow-to-yield circuits usable in stringent military applications.

Since the TO-3 package on this product cannot meet the cracked glass external visual criteria of MIL-STD-883 Method 2009, inspection for cracked glass at 100% external visual will not be performed. Instead a 100% fine/gross leak test will be performed just prior to shipment.
